> It's even worse if you have personal and business accounts tied to the same email address - you never know which one you're using, or which you need

I have a friend who managed to do get into this mess, and he's still not sure how he did it.

[email protected] is apparently linked to two separate identities at Microsoft, one is a business account, one is a "personal" account.

Every time he experiences any kind of login issue, this bites him :/
